-
Water-resistant
-
Tear-resistant
-
Longer-lasting (3–5 times more durable than paper notes)
-
Environmentally friendly, as they are recyclable after use

1. Transparent Window
Each note contains a clear see-through window with intricate designs that are extremely difficult to replicate.
2. Tactile Features
Raised ink on selected parts of the note allows visually impaired individuals to identify denominations by touch.
3. UV and Fluorescent Elements
Under ultraviolet light, specific sections of genuine Australian Dollar bills glow with distinct fluorescent patterns.
